This is an accelerated PSO (APSO), developed by Xin-She Yang in 2008. APSO does not use velocities or any inertia parameter.
A full program for solving nonlinear constrained optimization problem (welded beamdesign as an example) is provided, which can be extended to solve other continuous optimization problems..

Concise Beam is a complex and yet easy to use CAD application that enables users to design and analyze precast concrete beams.

The application performs its tasks in accordance to ACI 318, CSA A23.3 and AS3600 codes. Users can model cross-sections to meet their demands as well as create prismatic variations over the length of the beam.

Using Concise Beam you can choose from multiple beam layouts such as simply supported beams, cantilevers, load distribution and cast-in-place pours.

Two programs are attached: sa_demo demonstrates how the simualted annealing works for simple functions, while sa_mincon solves a welded beamdesign problem using simulated annealing, which can easily be used to solve other constrained optimization problems in engineering design..

StruCalc 8.0 is the next generation of structural analysis software. The intuitive interface combined with the power to design multiple span members using steel, wood, flitch beams or manufactured lumber propels StruCalc ahead of the competition.

This is the features page for StruCalc 7.0, a now outdated version of our software. To see what StruCalc 8.0 looks like please go to our homepage and follow the links from there.

Feel free to browse any of our detailed information pages by following the below links:
